17-4PH stainless steel is a martensitic precipitation hardening stainless steel. Its domestic brand name is 0Cr17Ni4Cu4Nb. This
material is renowned for its high hardness, high strength, and excellent corrosion resistance. It can be hardened through heat
treatment, and its typical chemical composition includes elements such as chromium, nickel, copper, and niobium.17-4PH stainless
steel is widely used in fields such as aerospace, chemical engineering, petrochemical industry, surgical instruments, flue gas
desulfurization and denitrification in power plants, and environmental dust removal. Surface treatments such as shot peening can
improve its fatigue performance, and electrolytic polishing and chemical oxidation treatments can further enhance its corrosion resistance.
Forming
Grade 17-4 stainless steel can be formed mildly.
Welding
Grade 17-4 stainless steel can be welded using common fusion and resistance welding methods. Oxyacetylene welding method is not preferred for welding this

17-4PH Introduction
17-4PH stainless steel is a martensitic precipitation hardening stainless steel. Its domestic brand name is 0Cr17Ni4Cu4Nb. Thismaterial is renowned for its high hardness, high strength, and excellent corrosion resistance. It can be hardened through heat

Forming
Grade 17-4 stainless steel can be formed mildly.
Welding
Grade 17-4 stainless steel can be welded using common fusion and resistance welding methods. Oxyacetylene welding method is not preferred for welding this alloy.
Heat Treatment
Grade 17-4 stainless steel is soaked at 1038°C (1900°F) for 30 min and cooled below 16°C (60°F) for complete martensite
transformation in the condition A. The condition A material is treated at 482°C (900°F) for 1 h followed by cooling. Solution
treated material is soaked for 4 h at specific temperature in H925, H1025, H1075, H1100, and H1150 conditions followed by cooling in air.
Solution treated material is soaked at 760°C (1400°F) for 2 h in the H1150M condition followed by cooling. It is again heated at620°C (1150°F) for 4 h followed by cooling.
Forging
Grade 17-4 stainless steel is forged at 1010°C (1850°F). Before performing this process, it is soaked at 1177°C (2150°F).
Post-work solution treatment should be performed before final hardening.
Hot Working
Grade 17-4 stainless steel can be hot worked using common processes. It is treated at 1038°C (1900°F).
Post-work solution
treatment should be performed before final hardening.
Cold Working
Grade 17-4 stainless steel can be cold worked using common techniques in spite of its high initial yield strength.
Annealing
Grade 17-4 stainless steel is annealed at 1038°C (1900°F) for 0.5 h followed by cooling rapidly.
Hardening
Grade 17-4 stainless steel has high ductility, and can be formed using all conventional techniques. Powerful equipments are
required for forming this alloy because it is stronger than the regular steel. Heavy-duty lubricants are used during cold working.
Applications
Grade 17-4 stainless steel is used in the following applications:
* Nuclear reactor
* Aircraft and gas turbines
* Oil field
* Chemical process components
* Paper mill
Cap Introduction
Cap Introduction
The socket weld cap is a pipe fitting that is welded to the end of a steel pipe to seal the pipeline. It is also known as a pipe cap, end cap, plug or pipe cover. The main materials include carbon steel, stainless steel and alloy steel. The specifications range from DN15 to DN1200, with a wall thickness of SCH10-SCH160, and comply with various international and domestic standards such as ASME, DIN, JIS, and GB/T.The external shape of the socket weld cap includes convex, conical shell, flat cover, etc. Among them, the convex pipe cap is further divided into hemispherical, elliptical, disc-shaped and spherical dome-shaped. It is fixed by welding to ensure the pipeline seal and is widely used in petrochemical, nuclear power, machinery, medical equipment, shipbuilding, pipeline and other fields.

Cap Produce Processing
1. Raw material inspection: Selecting materials (stainless steel), verifying the material, conducting physical and chemical tests, and performing flaw detection2. Cutting: Marking and cutting the material into circular blanks, cleaning the burrs and marking the furnace batch number 3. Heating: Control the temperature according to the material and maintain it until it is uniform. 4. Forming: Mainly through hot press forming (using a hydraulic press), and for thin-walled and small-sized parts, cold spinning can be used. 5. Forming and Trimming: Perform shaping while the material is still hot, cut the straight edges to the desired length, and ensure that the end faces are smooth and the dimensions are compliant. 6. Heat treatment: Carbon steel/alloy steel annealing/normalizing + tempering, stainless steel solution treatment, to eliminate internal stress 7. Groove processing: Machining V-shaped/U-shaped grooves, controlling key parameters such as angle and backing plate size 8. Surface treatment: Sandblasting for rust removal on carbon steel, acid washing and passivation for stainless steel, removing impurities and ensuring smoothness 9. Non-destructive testing: Surface MT/PT, internal UT inspection to ensure no cracks or other defects 10. Final inspection: Verify dimensions, appearance and hardness, and confirm compliance. 11. Labeling and Packaging: Mark the material, specifications, etc. and store the packaged items in the warehouse.
